Is Graphite a Diamond’s Best Friend? New Information on Material Transformation (Nov. 18)Science has yet to achieve the alchemist’s dream of turning lead into gold. But a group of re-searchers using the GeoSoilEn-viroCARS (GSECARS) and High-Pressure Collaborative Access Team (HP-CAT) facilities at the Department of Energy’s Advanced Photon Source (APS) at Argonne National Laboratory, may have found a way to turn ordinary soft graphite (source of the “lead” found in pencils) into a new, super-hard material that “looks” just like diamond.

Crystal Structure of SARS Protease Determined Using APS (Jul. 31)
Using x-ray beams from the U.S. Department of Energy's Advanced
Photon Source, Structural GenomiX, Inc., a San Diego, California-based,
structure-guided drug discovery company, has completed the
three-dimensional crystal structure of the main protease
from the Coronavirus that causes Severe Acute Respiratory
Syndrome.

HP-CAT to Lead the Way in New Research under NNSA Grant (Jul. 24)The High Pressure Collaborative Access Team (HP-CAT) at APS sector 16 will be a primary location for research carried our under a new grant from the National Nuclear Security Administration (NNSA). The $5.9-million, 2.75-year NNSA grant to the Geophysical Laboratory of the Carnegie Institution in Washington, D.C., under the Stewardship Science Academic Alliances program, will fund research into the behavior of materials under extreme pressure conditions at the Carnegie/Department of Energy Alliance Center (CDAC).

Dedicated APS Powder Diffraction Beamline Funded by DOE-BES (Jul. 23)
A new high-resolution powder diffractometer beamline will be
funded by the U.S, Department of Energy's Office of Basic
Energy Sciences for construction at APS sector 11-BM. The
beamline proposal and subsequent funding arise from the
department's general call for new instrumentation at x-ray
and
neutron facilities. This state-of-the-art, dedicated powder
instrument will be a part of APS facility beamlines that
provide
a majority of beam time (80%) for general users.

APS Research Fuels Engineering Interest (Jun. 5)
Award-winning research on the characteristics of fuel sprays from
injectors is one of the featured articles in the May 2003 issue
of Mechanical Engineering and on the Web site of that magazine.
The studies, carried out at APS's X-ray Operation and Research
beamline 1-BM and the Cornell High Energy Synchrotron Source,
revealed startling new information about fuel sprays, including
the presence of a shockwave as the spray leaves the injector
nozzle.

Ruzicka Appointed AOD Division Director (Jun.
5)William
G. Ruzicka has been appointed Director of the APS Operations Division
(AOD), effective April 21, 2003. Ruzicka, who has served for 11
years as Operations Manager for the Intense Pulsed Neutron Source
(IPNS), fills the position vacated by the unexpected death of
Antanas V. Rauchas in November 2002.

BioCARS Participation in the SPPS Project at SLAC/SSRL (Mar. 6)
The X-ray pulse length emitted by synchrotron sources such as the
APS is determined by the electron bunch pulse length, which in
turn is limited to about 100ps by essential, long-term stability
requirements on the electron beam. However, many interesting
structural processes in hard and soft condensed matter and in
biological systems occur on time scales shorter than 100 ps...
